Specification forming part of Letters Patent No. 106,579, dated August 23, 1870.

To all whom it may concern Be it known that I, EDWIN D.

The nature of my invention consists in providing a way by which the depth of the cultivator-teeth in the ground may be gaged by means of two screws in the axle of the wheels; also, in providing a lever, in the manner shown, to raise the machine over stones or other slight obstructions, or in turning corners, or upon the road.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct a square frame, as an ordinary square cultivator, and suspend the cultivator from the axle of the wheels; but, in order to adjust the depth or cut of the cultivator-teeth, the cultivator is adjusted by two screws in the axle, as shown at A in the accompanying drawing, and bya lever on the center of axle, as shown at B in the accompanyin g drawing. o By means of the lever and the adjustingscrews supporting the frame, the cultivator may be raised to pass an obstruction, or in turning or moving from place to place.

' hat I claim as my invention, and desire to secure by Letters Patent, is

The arrangement of the axle O with the adjustable screws A, frame D, and lever B, substantially as set forth, and for the purpose specified.
